I saw there are isoductile and anisoductile damage types in damask 2.0, what are their counterparts in damask 3.0. If I want to simulate the ductile damage of aluminum, how can I set it up in the material file of damask 3.0?
Hello, Unfortunately the ductile damage models has been removed from DAMASK 3.0.
We are working on a new ductile model and hope to publish the same soon.
Cc Cc It would be difficult to answer without looking at the files, and the parameters, loading conditions etc.
If you can share that, I can provide a better answer.
Additionally, you can query our helpdesk : [email protected]
There are other developers who can also help you.
Please try to follow the guidelines of asking questions in the helpdesk as outlined in https://damask.mpie.de/support/helpdesk.html
Cc Cc I have changed your loadfile to include the damage solver.
Also, your time step : t/N is way too big for damage simulations, infact any kind of simulation I think. Try reducing the time step. Damage models are very time step sensitive.
Cc Cc Yes, you have to initialize the phi in vti file, .ie., the initial conditions need to be specified. You can do this using the damask python library.
Here is the code to do it:
import damask
g = damask.Grid.load('Polycrystal.vti')'
g.initial_conditions['phi'] = 1.0 # assuming none of the points are damaged (pristine material), you can obviously change that.
g.save('Polycrystal.vti')
Now, this error should not occur.
Sorry, for the lack of documentation in the webpage. We are updating it.
Hello Cc, i am new to DAMASK and also interested in the damage simulation by DAMASK. I have problem to set Grid file for the damage_spectral_ini with a dataset of "phi". How can we set it?

Not sure which alpha version you are using:
For alpha-8:
import damask
g = damask.GeomGrid.load('Polycrystal.vti')'
g.initial_conditions['phi'] = 1.0 # assuming none of the points are damaged (pristine material), you can obviously change that.
g.save('Polycrystal.vti')
For alpha-7:
import damask
g = damask.Grid.load('Polycrystal.vti')'
g.initial_conditions['phi'] = 1.0 # assuming none of the points are damaged (pristine material), you can obviously change that.
g.save('Polycrystal.vti')
Hope this helps!
